Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Engine Oil Level

Remove the dipstick and wipe it clean.
Reinsert it and remove again to check the oil level.
If low, add the recommended oil type until the correct level is reached.

3. Inspect Oil Filter

Locate the oil filter and check for signs of leakage.
If leaking, replace the oil filter with a new one.
- Use an oil filter wrench to remove the old filter.
- Apply a thin layer of new oil to the rubber O-ring of the new filter before installation.
- Install the new filter, ensuring it is snug but not over-tightened.

4. Confirm Oil Type

Review the oil specifications used during the change.
Refer to the owner’s manual for the correct oil type (e.g., SAE 0W-30, 5W-30).
If incorrect oil was used, drain the oil and replace with the correct type.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any engine codes.
Monitor if the check engine light re-illuminates after a short test drive.
